Abstract
A vehicle includes an assembly for providing suspension and steering for a wheel. The assembly includes an inner knuckle and a steering knuckle. The inner knuckle is coupled to an upper control arm at an upper joint and a lower control arm at a lower joint, forming a double wishbone suspension. The upper joint and the lower joint define a first axis. The steering knuckle is coupled to the inner knuckle at a steering joint that forms or otherwise defines a kingpin axis. The steering joint includes a revolute joint, a ball joint, or both. The steering knuckle is configured to be engaged with a tie-rod coupled to a steering mechanism. The kingpin axis is nearer a center of the wheel than the first axis, thus preventing or otherwise limiting torque steer. The upper and lower joints are constrained from significant steering rotation by suitable bushings, anti-steer arms, or both.
